HENRY G. CADY, OF PINE BLUFF, ARKANSAS.

STALK AND CLOD CUTTER.

SPECIFICATION forming part of Letters Patent No. 393,292, dated November 20, 1888- Application filed June 7, 1888. Serial No. 276,337. (No model.)

To a/ZZ whom it may concern:

Be it known that I, HENRY G. GADY, a citizen of the United States of America, residing at Pine Bluff, in the county of Jefferson and State of Arkansas, have invented certain new and useful Improvements in Stalk and Glod Crushers or Cutters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invent-ion pertains to certain new and useful improvements in stalk, corn, and sod cutters, having for its object the provision of new and highly-efficient means for readily and thoroughly effecting the cutting of stalks, &c., by means of a series of knives operated simultaneously.

rIhe -invention comprises the details of con struction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims. a

In the accompanying drawings, Figure l is a plan view of my invention. Fig. 2 is a rear end view. Fig. 8 is a longitudinal sectional view on the line 00 or, Fig. l; and Fig. 4 is a transverse sectional View on the line yy, Fig. l.

Referring to the drawings, A designates the frame or body of my improved cutter, between longitudinal bars of which are secured on an axle, a, two carrying and operating wheels, a ai. These wheels have secured in circumferential grooves or recesses a3 thereof cross pins or rods c", those of one wheel being disposed at about midway between those of the other.

B designates a series of cutting-knives, se cured each by means of parallel keeper-plates Z b to the rear side of an inclined transverse bar, Zi, pivotally secured by apertured plates b2 to a cross-rod, b, the inward movement of said bar being limited by a curved end rod, b4.

Gis a horizontally-disposed shaft, composed of three sections, d d d, the end sections being connected to the central section by clutchjoints di, as shown. This shaft is preferably j square-shaped in cross-section, and has rounded portions which rest in grooves in the upper ends of inclined supporting arms or brackets cl3, attached to frame A. 'Io this shaft are secured short rods d4, to the outer rear ends of which are connected wires d', attached at their lower ends to the sliding knives B,

whereby by moving said shaft said knives will be raised and lowered simultaneously.

E E are short levers fulcrumed in crossrods e e, and to their rear ends are connected wires or chains c', secured at their upper ends to short rods c2 e2, attached to the front of the sections of the shaft C. The forward ends of these levers E are designed to project into the circumferential grooves of the operatingwheels a a2 and to come in contact with the cross-pins a4.

To the front of the frame A are secured the forward ends of spring arms or boards F, which are pressed under cross-staples f and bear at their free rear ends upon the upper edges of the knives B, whereby said knives are always quickly depressed or returned to their work after being elevated.

From the foregoing description it will be seen that the wheels will effect the movement of the levers E, which will cause the partial rotation of the shaft, thus effecting the raising of the cutter-knives, which, as soon as each lever is lowered or is freed from contact with the cross-pins of the wheels, are forced downward by the spring arms or boards F.

The object of the clutch-connection between the sections of the shaft C is that in turning the machine said shaft will continue to be operated by the outer one of the two wheels.

My invention is extremely simple, cheap, and durable, and, being composed of but few parts, is not liable to readily get ont of order.

I claim as my invention- 1. As an improvement in stalk-cutters, the series of cutting-knives, the shaft having connection therewith, the operating-wheels provided With circumferential grooves, cross-pins projecting across said grooves, and the levers engaging said cross-pins, and also connected to said shaft, substantially as shown and described.

2. As an improvement in stalk-cutters, the combination of the operating-shaft constructed in sections, having clutchconnections, the knives disposed in rear of said shaft,the levers, and the operating-wheels for imparting motion to said shaft through said levers, substantially as shown and described.

3. The combination, with the frame or body, of the series of cutter-knives disposed at the IOO rear of said frame or body, the operating-shaft, the levers, the operatingwheels imparting motion to seid shaft through said levers, and the spring arms or boards secured at their forward ends to said freine and bearing on the upper edges of said cutter-knives, substantially as shown and described.

4. The combination, with the frame er body, of the series of cutter-knives, the board to which seid knives are secured, the keeperplates b, the npertured plates secured to the rear side of said board, and the cross-rod for pivotally securing said board and apertured plates, substantially es shown and described.

5. The combination, with the frame or body,
